but on my mk1 I want to see all reaction of the motor and the fuel pump (inter pressure)
the motor set up is:
mk3 tdi "ahu" motor (origin 90hp)
gearbox 02a (tdi 90hp) => the 110 hp is short
0.230 nozzle and 220 tarage injector
the pump:
base of fiat croma 2.5 tdid (20mm axe)
hydraulic head in 11mm
thottle in 17mm (rover td)
drawer of rover td (the best ^^)
LDA home made
came plate tdi afn (the more agressive)

and kkk14 turbo of mk3 1.9 TD

I think with this set up have 150hp with 4.5 L/100 km

if you have an exemple of mounting?
the necessary equipement or if you have a set up ready to inject, I m a verry verry verry noob in C++

Yeah, the existing software can be used. customizing the display is very easy.
The only thing that has to be implemented is the use of the RPM sensor G28.
Do you know its output signal? does it use an 60-2 trigger wheel?
